This example FT011 large scale RC boat was powered by a 775 motor. The problem with 775 is that it is very heavy, and it needs at least 4S to give reasonable performance.  Still, from time to time it may be insufficient in handling a direct drive prop. We attempt to change to a gear […]

Fusion 360 is a cloud-based 3D modelling software platform by Autodesk Inc. As a multi-component part system that combines parametric, direct, and mesh modelling tools, it has a free license for non-commercial use, making it perfect for hobby modelling. This book is specifically tailored for RC (RC car to be specific). It includes contents and […]

There’s a particular magic to a motorcycle. The lean, the balance, the visceral connection between rider and machine as it carves through a corner. Now, imagine capturing that entire sensation in the palm of your hand, distilled into a buzzing, scaled-down package of pure adrenaline. This isn’t about watching a car go fast in a […]

If the on/off switch becomes inoperable for whatever reason, you may want to make another switch somewhere between the circuitry and the batteries. Below shows an example:

Apart from standard size servos, small RC boats may use smaller servos. You primarily care about the width (the longest dimension) since that is relevant to how the mount is placed. The smallest 9kg servo is 22mm. The slightly bigger servo is 30mm.    

We have to admit that 380 class motor pinion is indeed a frustratingly tricky situation to what should be a simple problem. During motor replacement, most of the time the only option for a pinion is to try and prise the stock press fit ones off the stock motors and fit them to the new […]

Manta Ray, Blazing Stars and the like all share the same DF01 chassis platform. It has limitations on the motor pinion to use. The max upper limit is 21. Our experience shows that a regular 540 with a 21 can cook the motor pretty fast. To go with a 21 pinion you better use a […]

This video shows it all. Generally, if your electronics are water proof and there is sufficient ground clearance, a buggy with a good body shell and a tray style chassis (such as the Tamiyas) should be able to survive rain water. Another vid showing a TT02 running under rain.

The photo shows a Tamiya TT02 front lower arm with its shaft bent due to a sideway crash. Super glue alone is never strong enough. You want to use a soldering iron to heat and melt part of the plastic so the bond can get stiffer and stronger. Along the process there will be bad […]

The good thing about ball joints in arms and linkages is that upon a crash it will take the impact and fall off … this way nothing will break. If it is a screw joint (which is most common in Tamiyas), something will have to break upon impact… Ball joints: Screw joints:
